Product Summary

Iron reducing couplings are pipe fittings designed to allow pipes of dissimilar diameters to be joined together. These fittings are typically used where small consumer or process feeder lines are joined into large supply circuits or where small diameter fittings are installed.
The reducing coupling used on steel pipes is generally steel casting with standardized threads cut into either end. These couplers will normally feature a simple, stepped down profile and screw onto the two lengths of pipe in the same way a standard pipe joint does. Reducing flange joints are also available and have a section of stepped diameter pipe between the two flanges. Welded reducing coupling designs are similar to screw on examples but feature no threads.
